To ai! 1l/filoni 'it may concern,.-

it known that l, ADOLPH W. SCHRAMMI, u citizen of the. United States, residingin liliverton, New Jersey, have invented certain Improvements in 'lfvfater-Heaters, of which the following is a specification.

- My invention rela-tos particularly to eleotricnl apparatus designed to heat a glues or otl'ier vessel containing liquid, one object being to Simplify the construction of the devine as well as to so arrange and construct the -various parte that the likelihood of their getting out of order Shell he reduced to o, minimum.

Another object of the invention is to provide e simple and compact device for regu .loting the low of current to the heating device intended for the reception of the liquid containing vessel to he heated.

lExtending through the plate B and in the present instancer on the same circular arc as thatv of the ratchet teeth, are a series of metallic contacts b, which are electrically irisulatcdfrom the said plate and connected to different points of the heating coil or winding placed on the cup C. This cup, as shown, consists of an inner member c and an outer member c', spaced some distance from it, there being in the cavity between these two structures any desired tor-rn of Windinfr usually consisting of a series of layers o? bare wire separated by mica or other suitable insulatiu r material. As illustrated diagrammatically in Fig. 6, this wire c2 has a number of taps leading to the various contacts b and from one end of it there is a connection extending to a relatively long contact b7 also mounted upon the plate B concentrically with the contacts b in a position to be engaffed b the plunger (L8. Similarly when the parts are assembled, the contacts b8 are engaged by the plunger a7.

The cup structure is held rigidly tothe plate B by means of screws c3, vas shown in Figs. 2 and 3, there being bosses projectin from the plate for the reception of said screws.

From the above description it will be seen that the'plate B with its cup structure C may be moved through an are of about 120, i

thereby causing the plunger a7 to move over the contacts b While the plunger as remains in engagement with the long contact (17. The ratchet teeth b4 are so designed relatively to their plunger am and to the various contacts-b that said plunger tends to cause the plate B to stop and be held in such positions that some one of the contacts b6 is fairly engaged by the plunger c?. By turning the plate B lwith its Ecup structure on the base structure A, it is therefore possible to regulate the length of the coil c2 which is in circuit between the terminals of the device, for under o )erating conditions the current from one of t e conductors a Hows through one of the rods d* to the plug a3 from whence it passes thrpugh the plunger as to the loner contact b7 and to one end of the heating coil c2. After )assing through a greater or Aless length of tliiscoil depending on that one of the contacts b which is engaged by the plunger e7, it flows through the second rod er* to the second conductor a9.

-As is obvious, the amount of heating of the cup C may be varied by turning the plate upon its pivot and so varying the length of the coil c2 which is heated.

lt is to be noted that one of the contacts b has no connection to the coil c`l and therefore acts as an off point for the switch.
